Benefits of Exterior Waterproofing

There are several advantages, but the main one is that outside basement waterproofing will permanently eliminate the issue if done correctly.

  • Cutting off the water supply

  • Reduces the risk that years of water seepage can cause structural damage to your foundation

  • Your basement's humidity is decreased, which cuts air conditioning and dehumidification expenditures.

  • A long-term remedy, not a quick cure

What Is Exterior Basement Waterproofing?

Exterior basement waterproofing is the removal of the soil surrounding a foundation and the construction of a fresh barrier on the outside of a block or poured concrete wall that prevents water from entering the foundation. We used to cover the foundation wall with a light coat of mortar. Still, nowadays, specialized rubberized coatings that will last for decades are put on top.

Why Waterproof Exterior Basements?

The majority of alternative waterproofing solutions only serve as temporary fixes. Whether you paint inside walls with waterproofing paint or use plastic sheeting to create a vapor barrier, the goal is to stop the water after it has already traveled through the wall. It can lead to structural problems and bring moisture one step closer to your basement, increasing the risk of damage to the walls, the carpet, and anything else you've kept there. Interior sump pumps have their place, but the best and most long-lasting solution is to prevent water from ever entering the interior space.

Considerations for Exterior Basement Waterproofing

From the first stages of planning through the project's conclusion, there are several things to be mindful of.

  • Electrical – Before starting a job, having all utility lines designated in the electrical and plumbing fields is always a good idea. It covers inbound phone and cable, gas, sewer, electricity, and sprinkler systems.

  • Landscaping – Do you wish to preserve your landscaping? You may need to replace more giant shrubs and trees because they occasionally do not survive the shift.

  • Access - Depending on the project's size, driving past neighboring yards or moving fencing could be required to go to the job location. Naturally, we will negotiate all of this before the project starts.

The Process of Exterior Basement Waterproofing

Here is a brief walk-through of what to anticipate when the A-1 experts arrive for your outside waterproofing service.

  • Excavation - For most houses, the initial step will be to remove any existing landscaping near the foundation. After, A small excavator will be used to dig down to the foundation's footer by hand or, depending on the scale of the job, bring one in. As the water drains down the outside of the foundation, it will flow off and away from the wall by being dug into a trench that is often even a few inches below the top surface of the footer.

  • Footer Drain - Our professionals will reinforce the dirt wall for security and fill the trench with gravel. A more significant 12" culvert pipe will frequently be inserted vertically in one end of the trench, supporting our footer drain, typically a 4" perforated pipe. We'll use this as our sump pump well. The pump will be accessible for future repair as needed since the pipe will ascend vertically to the top of the current grade. The drainpipe is around 2"-4" gravel after the 4". Fit the perforated pipe into the hole bored in the pump well.

    A sump pump with an extension pipe connected to the surface is lowered into the culvert pipe/pump well once the drain and pump well are in place. Installing the sump pump now is crucial because it cleans the surface of the outer wall. We need water during the following stage and a mechanism to pump the water out of the trench.

  • Cleaning and Tuckpointing – A hose or powerful pressure uses a pressure washer to clean the wall. Then, any gaps or damaged blocks are tuckpointed with cement to prevent water from seeping into the foundation.

  • Rubberized Coating - Apply the rubberized coating after the surface of the foundation wall has dried and any cement tuckpointing has hardened. Ensure the coating is above the final grade, covers the whole surface, and is evenly distributed.

  • Backfill – Following the rubberized coating's drying period, backfilling is necessary. Take care when backfilling to avoid scratching or damaging the new covering with large rocks or equipment.

  • Final Plumbing - The sump pump drain must be connected to existing downspouts or routed to a runoff area. The pump well is then covered with an access cap.

  • Replace Landscaping - At this stage, Clean the area and tamp down the trenched area.
